My Guyson sand blasting cabinet is excellent, but the perspex window constantly mists up externally from my breath. Especially in the current cold weather it becomes a right pain, but even in more normal times it's a problem. I have thoughts of installing some sort of blower to give a cross draught, possibly with a heater, but cannot find anything small enough not to be cumbersome.
Any suggestions welcome, but lets not start a heavy breathing thread!
